【摘要】 本文根据12V190Z型柴油机燃油系统的试验结果,分析了泵腔燃油充填不足对喷射过程的影响,提出了当泵腔内存在空腔时泵端边界条件的处理方法,并以计算结果和试验结果比较说明了这一方法的可行性。本文还对12V190Z型柴油机燃油系统提出五个改进方案。更多还原

【Abstract】 Based on the experimental results of the fuel injection system obtainedfrom a test diesel engine of type 12V190Z,this paper analyses the effectof the fuel pump insufficient feed on the fuel injection process,and putsforward a method to modify the fuel pump end boundary conditions whenthe insufficient feed phenomenon occurs.The feasibility of this method isproved by comparing the calculated values with the experimental results.At last,five schemes are offered to further improve the fuel injection systemof 12V190Z type diesel engine.更多还原
